5-5. Tensile strength of crimped section and measuring method
(1) Tensile strength of crimped section
Retention strength of the crimped wire when the pull force (N) is applied to it. The pull force is defined for each
style of the contact.
(2) Testing method of tensile strength
Secure the crimped contact on applicable fixture assuring that the wire can be freely pulled and the force can
be measured.
Apply pull at the rate of 20 to 80 mm per minute until the failure of the crimp section (wire pulled-out). The value
of the pull-out force must be higher than the minimum specified.
* Needs to satisfies specification of crimping quality standards for each of the contact for the specified values.
① The crimp height is in the specified range.
② The bellmouth has an is correct size.
③
The protrusion of the conductor is correct.
④ The outer insulation is inserted in the conductor barrel.
⑤ The outer insulation is correct crimped in the insulation barrel.
⑥ The conductor does not protrude from the wire barrel.
⑦ The contact section of the contact is not deformed.
⑧ The lance is not deformed.
⑨ The wire barrel has no noticeable burr.
⑩ The finished crimped section is free from any material crack or rough surface on the outside of the barrel.
⑪
The bend angle in the contact is as needs to satisfies specification of crimping quality standards for each
of the contact.
5-5. 压接部分的拉伸强度及测定方法
(1) 压接部分的拉伸强度
这是指拉伸芯线压接部分（钢线筒部分）的电线时，能够承受的强度，根据每个端子和每根电线设定允许值。
(2) 拉伸强度的试验方法
为了不让绝缘筒发挥功能，应压接让电线较长滑动的部分，安装于拉伸试验机，测定电线破裂时的数值。 （关于
电线的拉伸速度，请设定为 20mm ～ 80mm ／分钟。 ）
* 关于标准值，应确认每个端子的压接质量标准书的标准。
①
压接高度在标准内。
②
钟罩属于合理的大小。
③
芯线突出正确。
④
钢线筒上没有被覆陷入（深嵌） 。
⑤
被覆被正确压接在绝缘筒上。
⑥
芯线未从钢线筒溢出。
⑦
端子的接触部分没有变形。
⑧
枪头没有变形。
⑨
钢线筒部分没有大规模的毛刺。
⑩
压接部分没有龟裂且筒外侧面的表面不粗糙。
⑪
端子的弯曲符合每个端子的压接质量标准书的标准。
5-6. 确认压接后的端子形状
(1) 合格品的基准
5-6. Confirmation of the shape of contact after crimping
(1) Standards for acceptable crimp
